All releases of libESMTP

Release Notes: A certificate domain name comparison bug when wildcards are used was fixed. A subjectAltName comparison failure no longer falls back to commonName, which is now used only when subjectAltName is not present. The auto* file was tweaked for the current versions of these tools.

Release Notes: Added a missing check for STARTTLS if a server does not support ESMTP, revoked the deprecated status from smtp_option_require_all_recipients and fixed handling of the Hdr_PROHIBIT option.

Release Notes: A serious buffer overflow problem that could be exploited by a malicious SMTP server to overwrite the stack of an application linked to libESMTP was fixed. A minor bug in the replacement strn?casecmp functions and a compile problem in the NTLM code for platforms lacking stdint.h were fixed.
